What CRT did you see? The difference between a top of the line G90 and an old early 90's set like a Sony 1272 is huge. For comparison, a modern projector like a JVC RS65 will compare well to the G90,outperform it in some ways, not as good in others.
tons of info on the differences,do a search
I have done some searches but I couldn't tell if what I was reading was the view of enthusiasts with the rosy memories or something more objective. Most of what I read seems to be extreme views - either they are much better than digital projectors, or they are outdated junk.
I know there is a huge difference between the best and worst examples. The last one I saw was one of the top Runco ones. I forget the model but it was so long ago, that I'm not relying on that reference. I can't even remember what the source material was but I know we have better sources today which would be needed for a fair comparison.
Your reference to the JVC is helpful and you sound like you are being objective.
Can you tell me how they deal with the horizontal detail on a 1920 x 1080 image given that they are 4:3 aspect ratio devices? I would like to know if the 1080 lines they can produce with s 16:9 image is comparable to a native 1080p 16:9 projector or is it closer to one of those 1450 x 1080 projectors? I know the G90 has an input card which allows the use of an HDMI cable.
The other question is: why do people claim that they can produce "real blacks". Given that there is no such thing as black light and CRT's still use light to create the image, don't they have just as much trouble producing blacks on a white screen as modern devices?
On paper, it sounds great. No fixed number of pixels and the ability to add input cards means that a device with enough bandwidth would be future proof in a way that isn't possible with digital. I think I'm missing something though. If I fed it a 2.40:1 Blu Ray with 1920 x 800 dots, what level of detail can I create on an image that needs to fit inside a 4:3 raster? If I get to 800 vertical lines, what stops me having to chop off half the picture from the sides to fit it in?
If you had a G90 and found that you would have to go better than a JVC RS65 today to get better and that you were not even close to exhausting the bandwidth, you might feel like it was a good purchase!
